Under the ordinance, the maximum annual rent increase is called the Annual General Adjustment (AGA). The AGA is set at 60% of the percentage increase to the April Consumer Price Index (CPI) for the San Francisco-Oakland-Hayward region for the time period of September 1, 2023 to and through August 31, 2024. The AGA can never go above 5% or below 0%.
In most cases, the AGA will be lower than 5%. This year, the regional CPI published in April, 2023 was 4.2%. 60% of 4.2% is 2.52%, therefore, for the time period of September 1, 2023 to and through August 31, 2024 the maximum annual rent increase is 2.52%.
For the calculation effective September 1, 2024, the maximum rent increase is 75% of the March, 2024 CPI. The March, 2024 CPI increase is 3.8%. If you would like to review how the CPI is determined, see here. Seventy-five percent of 3.8% is 2.85%. Therefore the AGA for the time period from September 1, 2024 to and through August 31, 2025 is 2.85%.
